Description

Tire manufacturing method and facility for vehicle wheel

The present invention relates to a method and equipment for manufacturing tires for vehicle wheels.

A tire for a wheel generally includes a carcass structure shaped according to a substantially toroidal configuration comprising at least one carcass ply having axially opposed ends. The carcass plies are engaged with respective annular anchoring structures, each of which is typically at least one substantially circumferential annular insert, referred to as a "bead core", into which at least one filling insert is normally injected and which tapers radially away from the axis of rotation. is formed with The annular anchoring structure is in a region commonly identified by the designation "bead". The bead has an inside diameter corresponding substantially to the so-called "fitting diameter" of the tire on each mounting rim.

The tire also includes a crown structure comprising at least one belt strip positioned radially outboard to the carcass ply and a tread band radially outboard to the belt strip. Longitudinal and transverse recesses are typically formed on the tread band, and the recesses are arranged to define the desired tread pattern. Between the tread band and the belt strip(s) it is possible to insert a so-called “underlayer” made of an elastomeric material having properties suitable for obtaining a stable connection of the belt strip(s) with the tread band itself.

The tire also includes a pair of so-called sidewalls made of elastomeric material representing the axial outer surface of the tire with respect to the intermediate plane perpendicular to the axis of rotation of the same tire. For example, the sidewall presents an axial outer surface to at least a portion of the annular anchoring structure, the carcass ply(s), the belt strip(s) and optionally the tread band.

In a "tubeless" tire, there is at least one layer of elastomeric material, generally referred to as a "liner", that has gas-tight properties and generally extends from one bead to another, at a location radially internal to the carcass ply.

In the tire production cycle, after a manufacturing process in which various structural components of the tire itself are manufactured and/or assembled, molding and vulcanization processes configured to define the structure of the tire according to the desired geometric shape and tread pattern of the manufactured green tire are performed. It provides what is transferred to the molding and vulcanization line to be.

The term "elastomeric material" is meant to denote a composition comprising one or more elastomeric polymers and one or more reinforcing fillers. Such compositions may also contain additives such as, for example, crosslinking agents and/or plasticizers. Due to the presence of a crosslinking agent, these materials can be crosslinked through heating to form the final product.

The term "green tire" means a tire that has not yet been molded and vulcanized, obtained from a manufacturing process.

The term "finished tire" is meant to denote a finished tire that has been molded and vulcanized after obtaining from a manufacturing process.

The term "tire" is meant to denote either a finished tire or a green tire.

The terms "axially", "axially", "radially", "radially", "circumferentially" and "circumferentially" are used in reference to tires or drums used in the production process of tires. .

In particular, the terms "axial" and "axially" are meant to denote a reference/size that is arranged/measured or extends in a direction substantially parallel to the axis of rotation of the tire or drum.

The terms "radial" and "radially" are meant to denote a reference/size that is arranged/measured or extends in a direction perpendicular to the axis of rotation of the tire or drum and lies in a plane containing such axis of rotation.

The terms "circumferentially" and "circumferentially" are meant to denote a standard/size that is arranged/measured or extends along a circumference extending around the axis of rotation of the tire or drum.

The term "component" or "structural component" of a tire is meant to denote any part of a tire or portion thereof that is capable of performing its own function. Examples of structural components of a tire are: liner, underliner, wear resistant insert, bead core, bead filler, carcass ply(s), belt strip(s), underbelt layer, underlayer of tread band, sidewall, sidewall Inserts, tread bands, reinforcing elements made of fabric or metal reinforcement, elastomeric materials, etc. or parts thereof.

The term “carcass structure” is meant to denote a substantially cylindrically shaped sleeve comprising at least one carcass ply. Generally, the sleeve has axially opposed ends that engage respective annular retaining structures configured to form a bead of a tire. Preferably, each annular anchoring structure includes a substantially circumferential annular insert, referred to as a "bead core", into which at least one filling insert is preferably injected. Preferably, the carcass structure also includes at least one of a wear resistant insert, liner, underliner, composite, sidewall insert, stiffener, underbelt insert.

The term "crown structure" is meant to denote an assembly formed by at least one belt structure (comprising at least one belt strip) and a tread band.

The term “worked tire” is meant to denote a tire at any stage of its relative manufacturing process from manufacturing of at least one first component constituting the carcass structure and/or crown structure to obtaining a finished tire. .

The term "worked carcass structure" or "worked crown structure" refers to a process that proceeds in the manufacture of at least one first component constituting the carcass structure or crown structure until the carcass structure or crown structure is completely obtained, respectively. It is meant to indicate a carcass structure or crown structure at any stage of the relative manufacturing process.

The term "steady state operation" is meant to indicate the normal operating conditions of a tire manufacturing plant, excluding periods of possible temporary start-up or shutdown of the plant itself, eg related to production batch changes.

The term “semi-finished product” is meant to denote a pre-manufactured product to form the structural components of a tire (ie, prior to tire production, generally manufactured outside a tire manufacturing facility). The manufactured product is prefabricated in full width. That is, the semi-finished product has its own width pre-sized to be equal to the width (measured in the axial direction of the tire) of the structural component of the tire to which the semi-finished product is to be made. The manufactured product may be pre-manufactured in full length. That is, the semi-finished product may have its length pre-sized to be equal to the length (measured in the circumferential direction of the tire) of the structural component of the tire to which the semi-finished product is adapted.

In general, manufactured products have a profile with a flat cross section.

The term "basic semi-finished product" means continuous elongated and/or ribbon-like elements cut to size suitable for use in the on-site (inside a tire manufacturing facility) manufacture of structural components of a tire at the moment the tire itself is made. This basic semi-finished product has its own width smaller than the width (measured in the axial direction of the tire) of the structural component of the tire to be manufactured. These basic semi-finished products can be used in suitable quantities for the on-site manufacture of one or more of the structural components of the tire described above during the manufacture of the tire itself, without the need for pre-manufacturing and subsequent storage of the semi-finished product. To make the structural components of a tire, the basic semi-finished products are generally stacked side by side (ie one next to the other and/or at least partially radially juxtaposed) in a stacking plane. Thus, it is possible to manufacture the structural components of a tire simply by stacking suitable semifinished products and optionally cutting them to size, but they must be stacked side by side and/or juxtaposed on top of other basic semifinished products to make the structural components of a tire. impossible.

The term “technological flexibility” means the possibility of using for each tire different semi-finished/basic semi-finished products depending on the type of elastomeric material or type of fabric, metal or hybrid reinforcing cord.

The term "build cycle time" is meant to indicate the time that elapses between the exit of one tire being processed and the exit of the next tire being processed by the facility under steady state operating conditions.
